Verwirrt von den Zyklusbewertungen? Erfahren Sie genau, was "10% Arbeitszyklus" für Ihren linearen Aktuator bedeutet, wie Sie ON/OFF-Zeiten berechnen und professionelle Tipps erhalten, um eine Überhitzung des Motors zu verhindern und die Lebensdauer der Geräte zu verlängern.
Actuator duty cycle describes how long an actuator can run within a fixed time period before it needs to rest. For example, a 10% duty cycle often means the actuator can operate for 2 minutes and then rest for 18 minutes in a 20-minute cycle. Choosing the wrong duty cycle can cause overheating, unstable performance, or reduced service life.
Arbeitszyklus describes the permitted ON/OFF operating pattern under specified load, ambient and thermal conditions. The reference interval is product-specific; do not assume a universal 10-minute interval.
Motor operation generates heat, and allowable run/rest timing depends on the motor, gearing, load, speed, enclosure, ambient temperature and thermal design. Use the selected actuator’s documented duty-cycle condition rather than a generic analogy as an engineering limit.
Angenommen, Sie sehen „10% (2 Minuten EIN / 18 Minuten AUS)“ in einer Aktuatorspezifikation. Hier ist, was das bedeutet:
For a product explicitly rated “2 min ON / 18 min OFF,” that pattern should be treated as the documented operating limit under the stated test conditions. Exceeding it can increase thermal stress, but the exact temperature rise and failure mode depend on the selected motor and application.
Duty-cycle limits are often driven partly by thermal behavior. Motor winding, gearing, lubrication, enclosure and ambient conditions can all affect the allowable operating pattern. When a system exceeds its documented limits, possible effects include:
Higher temperature changes winding resistance and can increase thermal stress. Whether this becomes a runaway condition depends on the motor/control design, load, supply and cooling; do not assume destruction within a fixed number of minutes.
Motor insulation has temperature limits, and excessive thermal exposure can accelerate insulation degradation. Failure timing and mode depend on insulation class, temperature history and the complete motor design.
Higher temperature can also affect bearings, gearing and lubricants. The effect depends on the selected components, lubrication and actual temperature/time profile.
Repeated operation above the documented thermal limits can reduce component life, but there is no universal “every 10°C halves life” rule that should be applied to every actuator without the relevant motor/material data.
Duty-cycle specifications can be expressed in different ways. The examples below illustrate arithmetic only; they are not universal application recommendations:
| Example duty cycle | Illustrative ON time | Illustrative OFF time | How to use it |
|---|---|---|---|
| 10% | 2 min | 18 min | Arithmetic example only; confirm the selected product’s stated interval and conditions |
| 25% | 2,5 min | 7,5 min | Example over a 10-minute interval; product documentation may use another interval |
| 50% | 5 min | 5 min | Example over a 10-minute interval; not a generic “continuous-use” rating |
| 100% | Kontinuierlich | Keine | Only when the selected actuator/system is explicitly rated for continuous operation under the stated conditions |
Do not choose a duty cycle from broad labels such as consumer, light industrial or continuous-use. Derive the required ON/OFF pattern from the actual motion profile, load, ambient conditions and selected actuator documentation.
Die Auswahl des richtigen Arbeitszyklus erfordert ein Verständnis Ihres spezifischen Anwendungsfalls. Fragen Sie sich:
If the decision is specifically whether to trade faster movement against repeated-use capability, see Arbeitszyklus vs. Geschwindigkeit: Was die Auswahl von Linearantrieben wirklich antreibt. This page remains the reference for duty-cycle definition, arithmetic, documented ON/OFF interpretation, thermal limits, and operating-compliance questions.
Sit-stand desks: define actual travel time, expected adjustment frequency, load and controller behavior, then verify the selected column/actuator duty rating.
Industrial doors or access mechanisms: derive duty requirements from cycle frequency, travel time, load, temperature and required service profile; do not use a generic 25–50% recommendation.
Care-related or regulated equipment: finished-device duty, thermal, safety and regulatory requirements must be defined for the actual mechanism; there is no universal 50–100% actuator duty requirement.
Agricultural machinery: duty varies by mechanism and task; define the real cycle and environment rather than assuming a 25% minimum.
ActuLift actuator platforms are configuration-specific. For duty-cycle or thermal decisions, use the selected product’s approved load, speed, current, duty/thermal limits, ambient conditions and supporting documentation rather than a brand-wide durability assumption.
Do not assume a particular winding grade, slot design or thermal-conductivity advantage across all ActuLift motors. If thermal performance matters, request the selected motor/actuator configuration’s current, duty-cycle, temperature and validation data.
Bearings, gearing, lubrication and continuous-duty capability are product/configuration dependent. Confirm the selected design, duty limits, acoustic requirements and maintenance expectations instead of inferring longer life or quieter operation.
Do not assume every actuator has undergone the same thermal-cycling or beyond-rating test program. Request the test records, inspection scope or validation evidence applicable to the selected product and order when required.
Use the Schwere Linearantriebe category to identify candidate products, then confirm the selected build’s actual duty-cycle/thermal rating, load, speed and environmental conditions. The category name does not establish continuous or near-continuous operation.
Use these practices to stay within the selected actuator’s documented operating envelope. They are not a guarantee of service life:
Enforce the documented interval in the control logic where supported. A compatible controller or PLC can help the system respect the selected actuator’s stated ON/OFF condition instead of relying only on operator memory.
For controller candidates, review Steuerkästen und Controller, then verify compatibility, timing behavior, current limits and fault handling for the selected actuator and finished system.
Operate within the documented duty-cycle, load, speed, ambient and controller limits. If the real motion profile exceeds them, select a configuration explicitly rated for that profile rather than relying on extra rest later.
Follow the product’s specified OFF/cooling interval and ambient-temperature limits. Do not invent a cooling time that differs from the documented duty-cycle condition.
Load affects current, speed and thermal behavior, but there is no universal 50–70% sizing rule. Size the actuator from the actual static, dynamic, holding and safety-factor requirements plus the selected product’s approved load/duty data.
Use the documented supply-voltage range and size the power source, controller and wiring for rated/peak current and voltage drop. The effect of undervoltage depends on the motor/controller architecture and load.
Keep the actuator within its approved mounting/alignment, side-load and load-path limits. Mechanical binding or side load can change force, current, wear and thermal behavior.
Not if the selected product is explicitly specified as 2 min ON / 18 min OFF. Duty-cycle limits are defined by the manufacturer’s stated interval and conditions; extra rest afterward does not automatically make a longer uninterrupted run acceptable. Use the exact selected-product specification.
It can. Load changes motor current, speed and thermal behavior, but the relationship is configuration-specific. Use the selected actuator’s load/current/speed/duty data and any required derating rather than assuming a generic higher-duty or higher-force solution.
Stop operation and follow the selected product’s thermal/fault guidance. Excess temperature can indicate an excessive duty cycle, load, ambient condition, supply/control issue or mechanical binding. Do not assume every ActuLift model includes thermal protection; confirm the exact configuration.
Duty cycle is one selection input alongside load, speed, stroke, supply, controller, ambient conditions and mounting. Match the real motion profile to the selected actuator’s documented operating limits and validate the complete mechanism.
Use the Linearantriebe category to identify candidate product families, then confirm duty cycle, load, speed, stroke, controls and environment for the selected configuration.
For configuration review, provide the required ON/OFF profile, load, stroke, speed, supply, controller, mounting and environmental conditions so candidate products can be compared against current documentation.
Final actuator suitability depends on the selected configuration and finished-system validation.
